Question

Find the time in which the simple interest on Rs.12900 at 25/3 % per annum will be Rs. 3225​

Answer 1

Answer:

Simple Interest = Rs.3

Step-by-step explanation:

Given,

Principal Amount (P)= Rs.12900

Rate of Interest (R)= $\frac{25}{3}$%

Simple Interest (SI)= Rs.3225

Time= ?

Formula for finding the Simple Interest=$\frac{PTR}{100}$

By simplifying this formulae,

$T=\frac{SI*100}{PR}$

⇒$SI=\frac{3225*100}{12900*\frac{25}{3} }$

⇒$SI=\frac{3225*3}{129*25}$

⇒$SI=\frac{3225*3}{3225}$

⇒$SI=Rs.3$

Hope it helps you❤❤❤

Answer 2

T = SI x 100 / P x R = 3225x100/12900x 25/3 = 3225 x100/ 129 x 3/25 = 3225 x 3 /3225 = Rupees 3
